Overview of this book

Imagine being able to create accurate maps that look how you want them to, and use them on the Web or in print, for free. OpenStreetMap allows exactly that, with no restrictions on how or where you use your maps. OpenStreetMap is perfect for businesses that want to include maps on their website or in publications without paying high fees. With this book in hand you have the power to make, alter, and use this geographical data in a collaborative way from anywhere on the Earth.OpenStreetMap was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways. This book will allow you to take control of your own maps and use them smoothly. This book introduces the reader to the OpenStreetMap project and shows you how to participate in the project, and make use of the data it provides. No prior knowledge of the project is assumed, and technical details are kept to a minimum.In this book, you'll learn how easy it is to add your neighborhood to OpenStreetMap using inexpensive GPS equipment, or even no GPS at all. You'll find out how to communicate with other mappers working in the same area, and where to find more information about how to map the world around you.Once you have your area mapped, you'll learn how to turn this information into maps, whether for use in print or online, large or small, and with the details you want shown. The book describes several rendering methods, each suited to different types of map, and takes you through a tutorial on each one.

How OpenStreetMap Records Geographical Features


We should now have covered enough of the structures and theory in OpenStreetMap for you to be confident in drawing and tagging features.

We've covered the types of data you can record, as follows:

  • Nodes, representing point features

  • Ways, representing linear or area features

  • Relations, representing more complex features

We've also looked at the tagging system and how the community uses and manages it:

  • Tags describe a feature in a verifiable, objective way

  • Use editor presets and existing tags to describe features where possible

  • Look in the OpenStreetMap wiki to find tags for unusual features

  • You don't need prior approval to use a new tag if you need it

In the next chapter, we'll put these to practical use, along with examples of how to map using the most common editing applications.
